DEMOUNTABLE WHEEL-RIM.

Specification of Letters Patent.

Patented July 31, v1917'.

Application ined :rune 2s, 191s. serial No. 106,397.

mou'ntable Wheel-Rims, of which the foltransverse movement,

lowing is a specification, reference being had therein to theaccompanying drawings.

This invention relates to' improvements in demountable rims for wheels,one object` of the invention being the provision of a demountable rimfor carrying pneumatic tires and especially adapted for use upon motor4cars, and so constructed that'a plain band rim may be quickly and easilysecured to the felly 0r rim 0f a wheel and prevented from havingcircumferential or transverse movement.

A further object of this invention is the provision of a demountable rimstructure in which a plurality of locking members mounted foroscillation are carried by the rim or felly and have end engagingmembers for clamping the opposite sides of the demountable rim to holdsuch rim against while coperative means are carried by such` lockingmembers and the rim to lock the same against circumferential movementand at the same time assist in holding it from transverse movement.

In the accompanying drawings Figure 1 is a cross section through oneform of rim especially adapted for a suspension or wire type Wheelshowing the present invention in use thereon.

Fig. 2 is a section taken on line 2 2 of Fig. 1.

Fig. 3 is a perspective view of the oscillatory locking member per se.

Fig. 4 is a view similar to Fig. 1, showing the present constructionapplied to a wooden wheel.

Fig. 5 is a side eleva-tion of a portion of a wooden wheel showing thelocking end in locked position.

Referring to the drawings, and more particularly to Figs. 1, 2 and 3,the metal rim 10 which is similar to the construction shown anddescribed in my co-pending application, filed even date herewith, SerialNumber 106,398, has the openings 11 formed in the pressed steel bands 12with the portion 13 slit so that the cylindrical portions 14 of thelocking member 15 may be inserted before the edges 16 are bent inwardly.

Adapted to rest upon the bent in portions 13 is` the demountable rim 17having the inturned flanges 18 for receiving the rim engaging portions19 of the outer casing 20" which may be taken as indicative of anyform'V 'of pneumatic tire.

This rim throughout its length at equidistant points is provided withcentrally disposed openings 20 and depressions or recesses 21, whilecarried by each lockingmember 15 is a centrally disposed eccentricshoulder 22 which is adapted to seat withinthe opening 20 and thuscenter the rim, and at the same time hold it from circumferentialmovement, the twocams 23 beingsimultaneously engaged with thedepressions l21 .so as to coperate with theeccentric shoulder' inholdingthe rim in place.

I Carried upon the outer end of the locking member 15 are 'theV heads24, each Vone of which is provided with the hooked terminal 25 forengaging the flanges 18 of the demountable rim, the inner faces thereofbeing slightly cammed so that a wedging action is imparted to moresecurely hold the parts in the position as shown.

In the construction shown in Figs. 4 and 5, the wooden felly 26 isprovided withy the transverse recesses 24 at equi-distant points, andhas attached by means of bolts 28 to opposite sides thereof the twoannular bands or rings 29.

The locking member 15 which is similar to the member 15 and thecorresponding parts of which are primed, is operated in a similar mannerand mounted in the bands 29 so as to engage the demountable rim 17 in asimilarV manner, as heretofore described, and hold the rim and its tire20 in proper position.

From the foregoing description, it is evident that with a demountablerim constructed according to and embodying the present invention, thedemountable rim may e made so as to fit snugly upon the metal rim orwooden felly and be held thereto by means of the oscillatory members 15and 15 and without the complicated wedging structures that now impartradial .action to the rim, which, in this instance, is merely lockedagainst transverse and circumferential movement, and in such a mannerthat it is impossible to have the demountable rim mounted otherwise thanconcentric with the felly.

What I claim as new is l. In combination, a wheel having a fellyprovided with a plurality of transverse receptacles, a plurality ofoscillatory members mounted Vin said receptacles, each of said membersbeing provided with a plurality of cams, one of said cams heilig largerthan the other, and a demountable rim provided with a receptacle foreach of the larger cams, said demountable rim being disposed to fit uponthe felly and be locked from circumferential movement when engaged bythe cams of the oscillatory members.

2. In combination, a wheel having a felly provided with a plurality oftransverse receptacles, a plurality of oscillatory members mounted insaid receptacles, each of said members constituting a shank having uponeach end a rim engaging terminal and intermediate of the ends thereof aplurality of cams, one of said cams being larger than the other cam, ademountable rim having a plurality of receptacles for the larger camsand adapted to lit upon the felly and beV held from lateral andcircumferential movement when engaged by the terminals and the cams ofthe oscillatory members.

3. In combination, a wheel, two apertured annular plates carriedthereby, a plurality of oscillatory members mounted in said ap` erturedplates, an eccentric shoulder and a Y tric shoulders of the oscillatorymembersV and with recesses for receiving the cams,

the outer edges ofthe rim being adapted to be engaged by the lockingterminal'sof the oscillatory member.

4L. A Wheel, a felly, two apertured annular plates attached to oppositesides of the felly, a plurality of oscillatory members mounted in saidplates, each of said members beingk provided intermediate of Vits Vendswith aV plurality of cams, one of which is larger than the other, aterminal rim engagingV means upon both ends of eachA member andprojecting eXteriorly of the plates, and a dye-V mountable rim forfitting annularly of the plates and provided' with cam receptaclesl forthe larger cams, whereby when the cams are 1n engagement with the rimthe terminal hooks engage the edges of the rim and the rim is held fromcircumferential and lateral Y movements.

In testimony whereof I afHX my signature.
